they can from peripheral adipose tissue and delivered to active muscles via the bloodstream. During higher intensity exercise, intramuscular triglycerides can also be hydrolyzed to release fatty acids for subsequent direct oxidation.

What happens to triglycerides during exercise?

In the process, exercise Stimulates an enzyme, hormone-sensitive lipase, that dissolves lipid or triglyceride molecules into three unconjugated or free fatty acid (FFA) molecules and one glycerol molecule (Figure 1); this process of breaking down triglycerides is called lipolysis.

Where are the triglycerides used during exercise stored?

Triglycerides (TGs), stored in within adipose tissue and muscle fibersConsidered a major source of oxidized free fatty acids (FFA) during exercise.

When to mobilize triglycerides?

Lipolysis and mobilization of triacylglycerols

When glycogen stores in the body are depleted, the production of certain hormones stimulates the hydrolysis of lipids. Lipolysis is a metabolic pathway catalyzed by lipases by which lipid triglycerides are hydrolyzed into glycerol and three fatty acids.

Where do fatty acids end up metabolized during exercise?

Fatty acids are taken up by adipocytes, but glycerol and chylomicron residues remain in the plasma and are eventually removed from the circulation by liver.

Glycogen storage in liver and muscle decrease during physical activity; The longer and more intense the activity, the greater the rate and overall reduction in glycogen storage.

What are the two main factors that determine fuel consumption when exercising?

Fuel for Endurance Sports – Intensity

The main determinants of the relative contributions of carbohydrates and fats to exercise are Intensity and Duration. If we look at the effective intensity as exercise intensity increases, what we see is an increase in carbohydrate dependence.

What is the body’s number one source of energy when exercising?

carbohydrate It is the primary fuel for most types of exercise and the most important nutrient for athletic performance. Our bodies operate most efficiently with a balance of protein, fat, and carbohydrates, but adequate carbohydrates are a key source of energy for athletes.

How quickly can you lower triglycerides?
